Abstract:

The three production decline formulas proposed by J. J. Arps and the extended two production decline formulas are applied to carry out the production decline regression in Wa 20 block in Dawa Oilfield. The correlation coefficients of several regression equations are all greater than 0.8, and the results are close to the actual production. Typical hyperbolic decline is selected to forecast the future production decline situation. Aimed at the status quo of the oilfield development, the counter measure is put forward to slow the production decline.

Key words: rock, compaction, compression, undercompaction, abnormally high pressure, equivalent depth method, downward migration of oil and gas
